The repo starts by forking adilakhter/pandoc-acm-journal-template. Its latest update is 3 years ago. I make some changes, update the template files, and have this writeup. My start point is to update the template to support --citeproc instead of --filter pandoc-citeproc, introduced at pandoc 2.11.
It works with pandoc 2.17.
make main-full to build pdf from a standalone main-full.md
make main-outline to build pdf from a outline file main-outline.md, which includes main-section-intro.md.
See Makefile.
Here is the note for my attempt to understand the tool chain. It works under my current understanding and assumptions of tools used.
acmart (CTAN, github) is required by sigplan and other ACM groups. The official doc is here. acm also provides the source code with sample pdfs in this zip file.
acmart is usually included in the TeX distribution, so I remove acmart.cls acmart.bib from the original repo.
pandoc is a fancy tool to convert files between many markup format including markdown latex pdf. To convert to pdf, it uses tools in the Tex distribution e.g. pdflatex.
From the perspective of acmart, one can use natbib (by default). Package natbib is for formatting references and BibTex style file ACM-Reference-Format.bst is for BibTex processing. One can also use Biblatex (with setting natbib=false).
From the perspective of pandoc, when generating a latex file from markdown, an option and a template are used to determine which commands to generate for references. The option can be set from command-line argument pandoc --natbib or pandoc --biblatex or YAML metadata. The template contains fragments $if(natbib)$ ... $endif$ $if(biblatex)$ ... $endif$ which are enabled by these options. You can see \bibliographystyle{ACM-Reference-Format} \bibliography{references} for natbib and \printbibliography for biblatex to render the bibliography.
However, pandoc won't do the bibliography rendering by just specifying the pdf engine. See this discussion in 2018:
Pandoc doesn't run bibtex/biber for you when producing a PDF. If you use pandoc-citeproc, you can get a nice bibliography in PDF output (and maybe that's what you were doing when it worked before), but if you want to use native biblatex, you'll have to produce a .tex file and run latex and biber yourself. -- jgm
and this issue in 2016:
If you want pandoc to use pandoc-citeproc to generate the bibliography, don't use the --biblatex option. If you use --biblatex, pandoc will generate biblatex citation commands instead of resolved citations. You'll need to process the resulting latex file using biber, just as you would normally if you were using biblatex. If you want to go this way, you'll need to use pandoc to produce a latex file and issue the latex and biber commands manually. Pandoc doesn't attempt to run bibtex or biber if you choose a PDF output file. -- jgm
In short, with either natbib or biblatex, you may not have the bibliography in the pdf directly from pandoc. It also applies for output format since after all pandoc doesn't read the bibliography file.
This is what citeproc solves and that's why you need to choose one cite-method from citeproc, natbib, or biblatex. With citeproc, pandoc reads the bibliography file from the metadata and renders it according to the provided CSL(Citation Style Language) file. acm-sig-proceedings.csl can be found on GitHub.
The default latex template can be checked via pandoc -D latex.
These are multiple places to set key-values pairs in a YAML format. However, not any pairs are effective.
pandoc --default=FILE accepts a default file with restricted keys. metadata-files are used in default file, but not YAML metadata block of a document.
pandoc support merging files sequentially by pandoc section1.md section2.md .... To include a file, you may use a filter e.g. pandoc-include (used in this repo) or pandoc/lua-filter (not used here).
albatross 0x222A can check which font contain u+222A.
I hope to use unicode in markdown and have them rendered correctly in the pdf. It's more tricky if I also hope to keep the unicode in the html output, which means I would prefer to use ∪(U+222A) rather than $\cup$ in the markdown. Let's assume it's a valid requirement. This set-union symbol is not included in \usepackage[utf8]{inputenc}. Even it's in \usepackage[utf8x]{inputenc}, utf8x is not suggested any more.
acmart uses Libertine for text, Inconsolata for monospaced font and newtxmath for math. You may need to install it e.g. sudo apt install fonts-inconsolata. Fonts used can be checked from the output pdf via strings build/debug.pdf | grep FontName.

I realize the easy fix is to add basicstyle=\ttfamily in listings options \lstset{ }
Centering in markdown which results in a html class .center can be achieved by wrapping
::: {.center}
CONTENT
:::However, the centering is not in the pandoc ast yet for latex.
You can also hardcode the latex in the markdown as
```{=latex}
\begin{center}
`` `
CONTENT
```{=latex}
\end{center}
`` `
Or you can also config the listings as \lstset{xleftmargin=.2\textwidth, xrightmargin=.2\textwidth} which also centers the listing. See https://stackoverflow.com/questions/3106419/center-latex-lstlisting
It's sutble to have result like section 2 in both pdf and html. The result is 2 in pdf is usually computed by \ref{LABEL-FOR-THE-SECOND-SECTION} while html cannot compute it. I don't find a nice way to solve it. The pandoc extension for html has a problem: I don't want it in the pdf result. The current solution is I have to repeat it somehow like
Section `\ref{LABEL-FOR-THE-SECOND-SECTION}`{=latex}[`2`{=html}](#LABEL-FOR-THE-SECOND-SECTION)`
\makeatletter is unnecessary in .sty or .cls files, as the default catcode regime includes it
